    I am running Craftbkkit 1.7.10 and I noticed some time back, in July I think, that I suddenly came up with a massivecore folder as well as my mcore folder.

    I tried an update with massivecore.jar but that didn't work. I put the the massivecore.jar in the plugings folder and it updated the massivecore folder but when I boot it says massivecore is an ambiguous plugin. It seems like it was updating the massivecore folder if I was updating with an mcore.jar before.

    I noticed the Jenkins file for Oct 3rd or so is mcore-null.jar..

    I also notice in the mstore folder it seems to be keeping both mcore and massivecore and faction files up to date. Server seems to be functioning ok at the moment. Not sure why I have 2 folders running and which one I should be following or quite the right way to update at the moment. I do all testing of new things on a back-server so have not added new stuff to online server since 7/23. Thanks for any ideas you can give me.

    Another item, when I boot it is using MassiveCore 7.3.0 and updating the factions and the UUID's.

    A tip (not sure if allowed.. as I'm not posting a link :p) Click on on the most recent files. Then change the Id to 36 so from "/files/35" to "/files/36" Use at your own risk though as it's not approved.

    "DOWNLOAD: link removed by Eyamaz"

    What happened ?

    11 hours ago I saw the download link and told me : "oh perfect! I'll update my server tomorrow..." We are now tomorrow and no more link available :(

    The link for the patch of Faction is still ok.
